Document title

On the isotopic composition of late Cenozoic sea water

Authors(s) and Affiliation(s)



Up to one fourth of the isotopic change in foraminifera found in deep-sea cores (or some 0.3 /) may be due to a gradual change in the isotopic composition of the Antarctic and Greenland ice sheets. Therefore the peak-to-valley variation of the 0 of formanifera cannot be used as a measure of the size of glacial ice sheets or of sea level lowerings unless corrected for this factor. The early stadial of a glacial (e.g. Weichselian at around 55,000 B.P.) might have been more intense than as appears from uncorrected isotopic curves, and the last stadial (e.g. Weichselian around 18,000 B.P.) less intense.
